alpha2-macroglobulin, MAM, A2M, alpha2M
Alpha-2-macroglobulin is a protease inhibitor and cytokine transporter. It inhibits many proteases, including trypsin, thrombin and collagenase. A2M is implicated in Alzheimer disease (AD) due to its ability to mediate the clearance and degradation of A-beta, the major component of beta-amyloid deposits.

The involvement of the sigma-1 receptor in neurodegeneration and neurorestoration.
Wieloch et al., Lund, Sweden. In J Pharmacol Sci, Jan 2015
The sigma-1 receptor (Sig-1R) is a single 25 kD polypeptide and a chaperone protein immersed in lipid rafts of the endoplasmic reticulum (ER) where it interacts with mitochondria at the mitochondria-associated ER membrane domain (MAM).
Sigma-1 receptor: the novel intracellular target of neuropsychotherapeutic drugs.
Hayashi, Hamada, Japan. In J Pharmacol Sci, Jan 2015
Sigma-1 receptors are localized at the endoplasmic reticulum (ER) membranes that are physically associated with the mitochondria (MAM: mitochondria-associated ER membrane).
Origin and Diversification of Meprin Proteases.
Marín, Valencia, Spain. In Plos One, Dec 2014
Meprins are astacin metalloproteases with a characteristic, easily recognizable structure, given that they are the only proteases with both MAM and MATH domains plus a transmembrane region.
Novel subcellular localization for α-synuclein: possible functional consequences.
Przedborski et al., New York City, United States. In Front Neuroanat, Dec 2014
Mitochondria-associated membranes (MAM) have emerged as a central endoplasmic reticulum (ER) subcellular compartments where key functions of the cell occur.
Stress responses from the endoplasmic reticulum in cancer.
Nishitoh et al., Miyazaki, Japan. In Front Oncol, Dec 2014
More recently, the mitochondria-associated ER membrane (MAM), which is a site of close contact between the ER and mitochondria, has been shown to function as a platform for various intracellular stress responses including apoptotic signaling, inflammatory signaling, the autophagic response, and the UPR.
Isolation of Endoplasmic Reticulum, Mitochondria, and Mitochondria-Associated Membrane and Detergent Resistant Membrane Fractions from Transfected Cells and from Human Cytomegalovirus-Infected Primary Fibroblasts.
Colberg-Poley et al., Ioánnina, Greece. In Curr Protoc Cell Biol, Dec 2014
The mitochondria-associated membrane (MAM) fraction provides direct physical contact between the ER and mitochondria.
Alpha-2-Macroglobulin Levels in Gingival Crevicular Fluid Pre- and Post-scaling and Root Planing with Adjunctive Tetracycline Fibers in Chronic Periodontitis: A Randomized Controlled Trial.
Juneja et al., Ghāziābād, India. In J Contemp Dent Pract, Dec 2014
BACKGROUND: This split-mouth clinical study aimed to investigate levels of alpha-2-macroglobulin (a2M) in gingival crevicular fluid (GCF) of chronic periodontitis patients pre- and post-scaling and root planing (SRP) with or without adjunctive use of tetracycline fibers.
Diet1 functions in the FGF15/19 enterohepatic signaling axis to modulate bile acid and lipid levels.
Reue et al., Los Angeles, United States. In Cell Metab, 2013
Diet1 encodes a 236 kD protein consisting of tandem low-density lipoprotein receptor and MAM (meprin-A5-protein tyrosine phosphatase mu) domains and is expressed in the enterocytes of the small intestine.

Expression, purification and structural analysis of recombinant rBdh-2His₆, a spermadhesin from buck (Capra hircus) seminal plasma.
Cavada et al., Fortaleza, Brazil. In Reprod Fertil Dev, 2011

Requirements for mediator complex subunits distinguish three classes of notch target genes at the Drosophila wing margin.
Treisman et al., New York City, United States. In Dev Dyn, 2011
Genes activated by Notch signaling at the dorsal-ventral boundary of wing disc fall into classes affected differently by the loss of kinase module subunits. The distinctions do not result from different requirements for Groucho.
Relationship between production of acute-phase proteins and strength of inflammatory stimulation in rats.
Yamamoto et al., Sagamihara, Japan. In Lab Anim, 2011
Peak serum levels of alpha(2)-macroglobulin and alpha(1)-acid glycoprotein injected at 0.05 mL/rat were significantly lower than those at 0.2 or 0.4 mL/rat. No significant differences were observed for peak serum levels at 0.2 and 0.4 mL/rat.
Sigma-1 receptor chaperones at the ER-mitochondrion interface regulate Ca(2+) signaling and cell survival.
Su et al., Baltimore, United States. In Cell, 2007
The ER supplies Ca(2+) directly to mitochondria via inositol 1,4,5-trisphosphate receptors (IP3Rs) at close contacts between the two organelles referred to as mitochondrion-associated ER membrane (MAM).
The Notch transcription activation complex makes its move.
Kopan et al., Baltimore, United States. In Cell, 2006
These structures show that the ANK domain of Notch is an integral part of the transcription complex and supports MAM binding, whereas the RAM domain may trigger allosteric changes in the structure needed for the derepression of transcription.
Structures of complement component C3 provide insights into the function and evolution of immunity.
Gros et al., Utrecht, Netherlands. In Nature, 2005
The structures reveal thirteen domains, nine of which were unpredicted, and suggest that the proteins of the alpha2-macroglobulin family evolved from a core of eight homologous domains.
